6 Claims.

This invention relates to a dispensing container for roofing cement orother equivalent materials which may be spread in a line or band on aroof or other surface.

In laying roll roofing on a roof, it is the custom to apply to the uppermargin of each course a band or ribbon of roofing cement upon which issubsequently laid the lower margin of the course next above. This cementcovers and seals .the heads of the roofing nails and makes a tight jointbetween the overlapping portions of successive courses of the roofing.

It is an object of the present invention to provide a dispensingcontainer for roofing cement adapted to facilitate the application ofroofing cement to the upper margin of each course of roofing as laid.

It is a further object of the invention to provide a dispenser whichwill facilitate the formation of a substantially uniform ribbon or bandof cement on the surface to which it is applied.

It is a still further object of the invention to provide a can orcontainer for cement having an end wall shaped to facilitate thedispensing of the roofing cement, provision being made for readilypuncturing or opening the end of the can in such a way as to dischargethe contents of the can to cooperate with a spreading element by whichthe width and thickness of the ribbon of cement may be readilycontrolled.

For a more complete understanding of the invention, reference may be hadto the disclosure of an embodiment thereof in the description whichfollows and on the drawing of which Figure 1 is a perspective view of acan embodying the invention.

Figure 2 is a section similar to Figure 3 but showing the top of the canbefore it has been punctured.

Figure 3 is a section on the line 3-3 of Figure 2.

Figure 4 is a sectional view of a piece of roofing and a portion of thecan, showing the mode of application of the cement to the roof.

Figure 5 is a plan view of a dispensing can, showing a series ofperforations for the discharge of the cement.

The cement may be conveniently packaged in a suitable container such asa metal can It] which may be manufactured in the usual manner so as tohave circular end walls, one of which is indicated at I2. The side wallsand end walls may be crimped and soldered to form a flange l4 aroundeach end, this mode of construction of an ordinary can being accordingto customary usage.

(Cl. ill-"67.4)

In the end wall l2 means is provided for readily opening the can and forspreading the cement discharged therefrom so as to form a band or ribbonof substantially uniform width and depth. As shown, a triangular ridgeI6 is embossed on 5 the end wall l2 so as to project outwardlytherefrom. As indicated in Figures 2, 3, and 4, the ridge or embossmentl6 projects beyond the fiange M, so that, when the end of the can ispresented to a plane surface, the flange will not 10 interfere with theengagement of the surface by the ridge. The ridge may be of any suitableconfiguration and is preferably in the form of a closed geometricalfigure, a triangle being illustrated in Figures 1 and 5. The portion 18of the ridge, which is the long leg of the triangle, is preferablysubstantially on a diameter of the end wall l2. The other sides 20 and22 of the triangle are preferably of equal length and together form a V.The area 24 which is surround- 20 ed by the triangle I6 is depressedrelatively to the ridge, forming a shallow reservoir into which fluidfrom the interior of the can is discharged when the can is opened andinverted. In order to facilitate opening of the can, a line of weak- 25ness 26 may be provided in the area 24 parallel and adjacent to the sidel8 of the triangle. A screw-driver, knife or other convenient tool maythen be employed to form a suitable discharge slot 30 as illustrated inFigures 1 and 3. Other 30 kinds of apertures may also be made within thearea 24 for the discharge of fiuid from the container. For example, asshown in Figure 5, one

or more holes 32 may be punched by a suitable tool to provide for thedischarge of the contents 35 of the container.

When a course of roofing has been laid and is ready to receive a band ofcement along its upper margin, the can Ill may be opened by making oneor more suitable discharge apertures. within the area 24. The can isthen inverted and presented to the roofing as indicated in Figure 4. Theliquid cement within the can then fiows out through the apertures undergravity and fills the reservoir defined by the triangular ridge I6 andthe depressed area 24. The can is then moved along the margin of theroofing in such a direction that the side 18 of the triangle leads, andthe V formed by the sides 2|] and 22 follows. The side I8 is preferablyat right angles to the path of motion of the can so that the sides 20and 22 act as applicator elements to spread the cement and regulate thethickness of the film applied to the roof. The can may be moved alongwith the side l8 contacting the surface to act as a spacing guide, thecan being slightly tilted to regulate the spacing of the sides 20 and 22from the surface.

It is evident that various modifications and changes may be made in thespecific embodiment of the invention herein shown and described withoutdeparting from the spirit or scope thereof as defined in the followingclaims.

I claim:

1. A dispenser for roofing cement or the like, comprising a sheet metalcontainer having an embossed ridge in one end wall thereof forming aclosed geometrical figure and projecting sufficiently from said end wallto engage aplane surface to which said end Wall of the container ispresented.

2. A dispenser for roofing cement or the like, comprising a containerhaving an end wall with a raised ridge thereon in the shape of atriangle surrounding a relatively depressed area adapted to be providedwith an opening to form an outlet for the contents of the container.

3. A dispenser for roofing cement or the like, comprising a containerhaving a sheet metal end Wall with a ridge embossed thereon in the formof a triangle with one. side approximately diametrical with respect tosaid end wall, said ridge surrounding a relatively depressed areaadapted to be punctured to provide an outlet for the contents of thecontainer.

4. A dispenser for roofing. cement or the like, comprising a containerhaving an end wall with a raised ridge thereon forming a closedgeometrical figure, part of which is in the form of a V, said end Wallhaving a relatively depressed area surrounded by said ridge and adaptedto be provided with an aperture for discharge of the contents of thecontainer.

5. A dispenser for roofing cement or the like, comprising a containerhaving a sheet-metal end wall with a triangular ridge embossed thereonand surrounding a relatively depressed area, said area having a weakenedline extending parallel and adjacent to one side of said triangle tofacilitate the formation of a slot through said end wall for thedischarge of the contents of said container.

6. A dispenser for roofing cement or the like, comprising a containerhaving a sheet metal end wall provided with means for forming therein aslot for the discharge of the contents of the container, and meansincluding a portion of said end wall embossed outwardly in the shape ofa ridge for spreading the contents of the container on a surface to forma band of predetermined width.
